Why?

I have a vet. even with det pistons you are at 9:3.1 and around 9:8.1 with stock de pistons. Non of these will have valve reliefs or will be forged. Cp does not make a 9:5.1 off the shelf ve piston.

U have a vet or a ve head on det bottom?

I have a built ve-t. ve block,head and de crank.

20+ with the fuel and tuning we have available now there is no need to be scared of high comp boosted motors.

I love the feel of a stock de+T

I refuse to go any less than 9.5:1. The driveability is much improved the higher the compression you have and it also helps with spoolup time.
